Abstract

Systems, devices, and methods are disclosed for the cleaning of an endotracheal tube while a patient is being supported by a ventilator connected to the endotracheal tube for the purpose of increasing the available space for airflow or to prevent the build up of materials that may constrict airflow or be a potential nidus for infection. In one embodiment, a method for cleaning endotracheal tubes comprises inserting a cleaning device within an endotracheal tube while a cleaning member is in a compressed position, radially expanding the cleaning member to an expanded position within the endotracheal tube, and withdrawing the cleaning device from the endotracheal tube with the cleaning member in the expanded position.

Claims

1. A cleaning device for removing biofilm from a body-inserted medical tube comprising:

an elongate body comprising a distal end and a proximal end;

a cleaning member positioned along the elongate body,

wherein the cleaning member is selectively movable between a radially-collapsed configuration and a radially-expanded configuration,

wherein the cleaning member, when in the radially-expanded configuration, comprises a generally rounded profile,

wherein at least a portion of the cleaning member is configured to circumferentially contact an interior surface of the medical tube when in the radially-expanded configuration,

wherein the portion of the cleaning member that is configured to circumferentially contact the interior surface of the medical tube comprises a generally smooth surface,

wherein the cleaning member, when in the radially-expanded configuration, is configured to remove biofilm from the medical tube as the elongate body is withdrawn from the medical tube; and

a suction channel extending along an interior of the elongate body, the suction channel comprising at least one port.

2. The cleaning device of claim 1, wherein the cleaning member comprises an inflatable balloon.

3. The cleaning device of claim 1, further comprising a light and a camera.

4. The cleaning device of claim 1, wherein the at least one port is located at a location along a length of the elongate body.

5. The cleaning device of claim 1, further comprising a visualization channel extending along a portion of the elongate body, the visualization channel having a window at a distal end of the visualization channel, and the visualization channel being configured to facilitate visualization of the interior of the medical tube.

6. The cleaning device of claim 1, in combination with a multi-port adapter comprising a first port configured to couple to a ventilator, a second port configured for insertion of the cleaning device, and a third port configured to couple to the medical tube.

7. The combination of claim 6, wherein the second port comprises an elastomeric diaphragm configured to prevent loss of ventilator tidal volume.

8. The cleaning device of claim 1, wherein the at least one port is located along the cleaning member.

9. The cleaning device of claim 1, wherein the distal end of the elongate body comprises a closed distal tip.

10. A cleaning device for removing biofilm from a body-inserted medical tube comprising:

an elongate body comprising a distal end and a proximal end;

a cleaning member positioned along the elongate body,

wherein the cleaning member is selectively movable between a collapsed configuration and an expanded configuration,

wherein the cleaning member, when in the radially-expanded configuration, comprises a rounded profile,

wherein at least a portion of the cleaning member is configured to circumferentially contact an interior surface of the medical tube when in the expanded configuration,

wherein the portion of the cleaning member that is configured to circumferentially contact the interior surface of the medical tube comprises a generally smooth surface,

wherein the cleaning member, when in the expanded configuration, is configured to remove biofilm from the medical tube as the elongate body is withdrawn from the medical tube; and

a suction channel extending along at least a portion of the elongate body, the suction channel comprising at least one port.

11. The cleaning device of claim 10, wherein the cleaning member comprises an inflatable balloon.

12. The cleaning device of claim 10, wherein the at least one port is located at a location along a length of the elongate body.

13. The cleaning device of claim 10, wherein the at least one port is located along the cleaning member.

14. The cleaning device of claim 10, further comprising a visualization channel extending along a portion of the elongate body, the visualization channel having a window at a distal end of the visualization channel, and the visualization channel being configured to facilitate visualization of the interior of the medical tube.

15. A cleaning device for removing biofilm from a body-inserted medical tube, the cleaning device comprising:

an elongate body comprising a distal end and a proximal end;

a cleaning member positioned along the elongate body,

wherein the cleaning member is selectively movable between a collapsed configuration and an expanded configuration,

wherein the cleaning member, when in the expanded configuration, comprises a rounded profile,

wherein at least a portion of the cleaning member is configured to contact an interior surface of the medical tube when in the expanded configuration,

wherein the portion of the cleaning member that is configured to contact the interior surface of the medical tube comprises a smooth surface,

wherein the cleaning member, when in the expanded configuration, is configured to remove biofilm from the medical tube as the elongate body is withdrawn from the medical tube; and

a suction channel extending along at least a portion of the elongate body.

16. The cleaning device of claim 15, wherein the cleaning member comprises an inflatable balloon.

17. The cleaning device of claim 15, wherein the suction channel comprises an opening located at a location along a length of the elongate body.

18. The cleaning device of claim 15, wherein the suction channel comprises an opening located along the cleaning member.

19. The cleaning device of claim 15, further comprising a visualization channel extending along a portion of the elongate body, the visualization channel having a window at a distal end of the visualization channel, and the visualization channel being configured to facilitate visualization of the interior of the medical tube.

20. The cleaning device of claim 15, further comprising a light and a camera.
